Expression of RPMS12 gene, coding for a mitochondrial
ribosomal S12 protein is controlled at level of transcription,
splicing and translation in response to as yet unidentified
signals mediating growth, tissue specificity and metabolic
requirements.For this mRNA three splice variants of 5'UTR
have been detected with only the shortest one found to be
regulated by growth status. A 26 nt tract was found to be
essential for post-transcriptional down-regulation, in
growth-inhibited ce......
